I've owned a Turbo II for at least 10 years. I like how quiet it is, it's suction, automatic start up with power tools, and it's portability. What I don't like is the cloth bag. It lulls you into a false sense of security. Initially, it does such a good job that you feel you don't need any other filters. However, over time the plastic edging on the top of the bag that forms the seal with canister starts developing cracks. If you don't notice them and you use the vac for vacuuming up drywall dust the dust will work it's way into the motor. You CAN vacuum drywall dust if the bag seal is intact, and while I didn't make a habit of it, I did do it occasionally while on a job. My vac still runs, but it is a bit noisier. My advice, a great vac, but if you'll be using it for drywall or other abrasive dust, get the disposable bags and HEPA filters.
